About Barium Carbonate

Barium carbonate is the inorganic compound with the formula BaCO3. It occurs as the mineral known as witherite. It is a white salt that is poorly soluble in water. Barium carbonate is made commercially from barium sulfide with by treatment with sodium carbonate at 60 to 70 °C or with carbon dioxide at 40 to 90 °C. Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts.

Barium carbonate is mainly used to remove sulfate impurities from feedstock of the chlor-alkali process. It is widely used in the ceramics industry as an ingredient in glazes. In the brick, tile, earthenware and pottery industries barium carbonate is added to clays to precipitate soluble salts that cause efflorescence.
